The last of the Calabrian "Greeks"

[Angela]

It's a sad story. There are only a few hundred speakers of Greko left, and most of them are old. No one forced them to give up their language, but events conspired against them. Their refuge was an area with no economic possibilities whatsoever, so to survive they had to leave. Greko became less and less practical. That it is documented at all is largely thanks to a young woman taught Greko by her father who is low a linguist at Cambridge. Attempts by people from Greece to teach people modern Greek backfired. It is its own language with its own history.

This is the area of the Aspromonte mountains. One of the lines in my husband's family tree traces to there, as does that of Raoul Bova.

Spoken Greko, not to be confused with the Griko of the Salentino in Puglia:

So if we consider, the lost of Connection with rest Greek speakers and language around 1100 AD
and the change of liturgy language around 1550,
means that in about 450 years Greco and Grico become different dialects?
or was it from before? or another reason?
